  Purpose

Sleep apnea is common among veterans with cerebrovascular disease (stroke or transient ischemic attack [TIA]), leads to hypertension, and is associated with recurrent stroke and death. Although continuous positive airway pressure (CPAP) safely treats sleep apnea, few veterans with cerebrovascular disease are diagnosed with sleep apnea or offered treatment.

Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1
The intervention group received unattended polysomnography and auto-titrating CPAP if sleep apnea was diagnosed
Procedure: CPAP Therapy for Newly Diagnosed Obstructive Sleep Apnea (OSA)
Continuous Positive Airway Pressure (CPAP) is provided for those patients who are diagnosed with OSA.
Arm 2
The control group received usual clinical care which may include receipt of sleep diagnostic and therapeutic services
Procedure: CPAP Therapy for Newly Diagnosed Obstructive Sleep Apnea (OSA)
Continuous Positive Airway Pressure (CPAP) is provided for those patients who are diagnosed with OSA.

Detailed Description:

The project seeks to evaluate whether a diagnostic and therapeutic intervention strategy among veterans with cerebrovascular disease and hypertension using unattended polysomnography and auto-titrating CPAP with a targeted adherence evaluation and educational protocol results in: an improved rate of diagnosed sleep apnea, an improved rate of treated sleep apnea, and lowered mean 24-hour systolic blood pressure. Secondary aims include: to determine whether the intervention strategy reduces the number of antihypertensive medications; to collect data supporting a cost-effectiveness evaluation if the intervention strategy is effective; and to determine whether the intervention strategy reduces daytime sleepiness.
